Arc Flash Hazard Risk Analysis

arc flash safety suit

To increase site safety, we provide a turnkey approach for Arc Flash Hazard Risk Assessment that includes data collection, analysis, reports and recommendations, applying settings and providing custom arc flash labels. Mitigating the threat from arc flash is critical, and our systems engineers will calculate the incident energy and arc flash boundary for each location in a power system. We also provide training for your personnel including defining safe working distances and suggested personal protection equipment (PPE) recommendations.

Our goals are to design safer power systems while adhering to all major standards including NFPA 70E, NEC, OSHA, NFPA, IEEE, and NESC. Avoid potential fines, lost productivity, and increased insurance and litigation costs with expert arc flash hazard risk assessment from Quad Plus.



Power Quality Study

A Power Factor Correction Study and a Harmonics and Flicker Analysis are used to ensure smooth, reliable electrical energy and to identify any sources of disturbances. These studies will not only assure the safety of your crew and equipment, but will also pay for themselves by eliminating any potential power factor penalties that may be incurred from the utility.

Harmonics and Flicker Analysis

A harmonics analysis determines whether harmonic currents and voltages exceed recommended limits as defined by IEEE 519 and whether remedial actions are necessary. The study typically includes on-site harmonic distortion measurements, data collection, power system modeling, and engineering analysis, and a report with results and recommendations. Examples of these solutions include the installation of tuned harmonic filter banks, phase shifting, and zig-zag transformers.

Power Factor Correction Study

When it becomes necessary to increase the capacity or efficiency of your system or improve voltage profiles, a power factor correction study will evaluate the ability of your power system to supply the connected load for operating conditions. The study will determine the real (kW) and reactive (kVAR) power flow and power factor through each branch of your power system. This data from this study is used to determine the following:

  • Reactive power flows
  • Need, ratings, and location of capacitors for power factor correction
  • Basic economic analysis and payback period for recommended equipment

Power System Study

The goal of a power system study is to ensure efficient and reliable power systems for your facility under both normal and abnormal conditions. The Power System Study is made up of several engineering analyses and investigations:

Coordination Study

Minimizing hazards to your crew and your equipment and reducing disruptions and outages to the power system is always a priority. A coordination study can achieve this by verifying the clearing characteristics of protective devices such as fuses, circuit breakers, and relays. We can also determine settings for protective relays, breaker size, and fuse ratings to ensure a safe environment.

Short Circuit Studies

Unusually high currents that occur during a short circuit event can exceed the capability of protective devices and lead to extremely dangerous situations--even explosions. A short-circuit study will analyze your electrical system to determine the magnitude of currents that can flow during an electrical fault and compare those values to the ratings of your equipment. Corrective action is recommended when necessary.

Load Flow Study

A load flow study determines the voltage, current, active power, reactive power, and power factor in each line or branch of your power system. During the design phase of a new project or when evaluating changes and additions to your current system, a load flow study is necessary to ensure system voltages and current remain within safe limits and whether additional equipment or services will be required.

Transient Motor Starting Analysis

When motors are started, current five to nine times higher than normal operating current flows through the system. This inrush of current can cause a drop in voltage that may prevent the motor from starting and may cause other motors to slow or stall. To avoid unnecessary wear on your motors and extend their working life, a transient motor starting analysis will determine whether your system can start the motor successfully or whether compensation is needed during startups to avoid slowing, stalls, and wear to your motors.
